This study uses a large eddy simulation(LES) model to investigate the turbulence processes in the ocean surface boundary layer at Zhangzi Island offshore.Field measurements at Zhangzi Island(39°N,122°E) during July 2009 are used to drive the LES model.The LES results capture a clear diurnal cycle in the oceanic turbulence boundary layer.The process of the heat penetration and heat distribution characteristics are analyzed through the heat ilux results from the LES and their differences between two diurnal cycles are discussed as well.Energy balance and other dynamics are investigated which show that the tide-induced shear production is the main source of the turbulence energy that balanced dissipation.Momentum ilux near the surface shows better agreement with atmospheric data computed by the eddy correlation method than those computed by bulk formula.

摘 要: 英语专业学生思辨能力匮乏是一种通病,在英语写作过程中症状尤为明显,这主要归咎于英语写作教学方法、写作内容任务、写作评价体系及学生学习方法等几大方面的诟病,为此,需要对以培养思辨能力为导向的英语写作教学进行教学模式的探讨和革新,主要包括思辨能力培养的因素注入教师能力提高、阅读写作口语一体化、关注学生写作过程及形成科学的写作教学评价体系等。  关键词: 写作教学 思辨能力 思辨缺席  思辨能
